Specification of Letters Patent.

Patented Feb. 28 1 .811.

Application filed January 28, 180%. Serial No. 474,667.

To all whom it may concern:

Be it known that l. FRANK B. \Vnnnxvnn, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented new and useful Improvements in Handcu it's, of which the following is a specification.

Tlhis invention relates to improved locks for hand-ends or similar manacles and re sides in the novel construction and arrangement of parts hereinafter fully described and claimed.

The primary object of the invention is to provide a locking device whereby the hasp of the out? cannot be swung open except by a person having a proper key and understanding the manner of of an auxiliary lock w1thin the key-hole opening of the hand cull".

dfith the above, and other objects 111 View, which will appear as the description progresses, the invention resides in the novel construction and combination of parts hereinafter fully described and claimed.

In the accompanying drawings, Figure 1 is a top plan view of a cull or manacle provided with. my improvement. Fig. 2 is a similar view of one of the manacles taken upon an enlarged scale and illustrating its central portion or chamber in section to illustrate the hasp locking mechanism. Fig. 3 is a transverse sectional view upon the Fig. i is a horizontal sectional view upon the line l1-l1 of Fig. 3.

In the accompanying drawings the numeral 1 designates a hand-cud. This end or manacle may be constructed of any particular or desired formation, and it is to be understood that I do notlay any claim to the cult except in combination with the improved locking mechanism hereinafter to be set forth. The cull 1 herein illustrated is of that class commonly employed by police oflicials and in order to clearly set forth the improvement, a brief description of the said cuff is deemed necessary.

The numeral 2 designates the shackle member of the end which is provided with the usual teeth and which has one of its ends pivotally connected with the body? as at 4-. The teeth. 5 of the shackle member are adapted to be engaged by the tooth 6 of a spring-pressed dog which is positioned within a chamber 7 formed by the body. The upper wall of thesaid chamber is provided with a slot or opening 9 arranged diositioning the bitv rectly above the dog (5, while surrounding this opening and connected with the upper outer wall of the chamber is a cylindcr 10. This cylinder 10 is provided with a bore 11 which is positioned directly above the keyhole opening 9. The bore is adapted for the reception of a barrel 12 which is provided with the usual key opening 13 adapted for the reception of a removable key. which in this instance it has not been deemed necessary to illustrate. The barrel 12 is provided with a plurality of spaced openings arranged at a substantially right, angle to the bore thereof. and the cylinder 10 is also provided with suitable bores or depressions 15 alining with the openings in the barrel. The openings within the barrel and cylinder are adapted for the reception of sliding pins 14. and 16.. and the pins 16 are normally forced outward from their bores into engagement with the openings provided in the barrel and also caused to contact the pins 14- of the said barrel through the medium of suitable springs 17. The barrel 12, below the key opening 13, is provided with a reduced extension 18. and this extension has its end provided with a bit 19. This bit 19 is normally positioned within a segmental chamber 20 formed in the lower portion of the cylinder. which is positioned directly above the keyhole opening 9 provided in the casing 8 of the curl". The reduced portion of the barrel as well as the bit formed thereon is of a size adapted to snugly pass through the keyhole slot when the bit is to be forced downwardly within the chamber 7 so as to allow the bit to contact with the dog 6 to swing the latter out of engagement with the teeth of the hasp. in a manner presently to be described. This cylinder 10 is provided with an offset or shoulder directly above the segmental chamber and surrounding the reduced portion of the barrel and having one of its end convolutions contacting the shoulder provided upon the cylinder 10 and its opposite convolution engaging the shoulder of the barrel 12 is a helical spring 22, which is adapted to normally force the barrel 12 upwardly so as to have its openings alining with the openings of the cylinder and to bring the pins of the cylinder into engagement with the pins of the barrel.

llrictly stated, the operation of the device is as follows: A notched key is inserted within the opening 13 of the barrel 12 so as to force the pins it against the springpressed pins 16 to allow for the rotation of the barrel. \Vhen the barrel is rotated so as to bring the bit into alineinent with the opening 9,-the barrel is forced downwardly and rotated so as to swing the tooth of the dog 6 out of contact with the teeth 5 of the shackle member 2, thus allowing the shackle to be swung free of the body member. \Vhen the shackle member has been opened the key is rotated in an opposite direction so as to bring the bit below the key-hole opening 9, when the pressure of the spring 22 will cause the barrel to move upwardly from the chamber 7 of the body of the shackle within the segmental chamber 20, the said upward movement being limited by the ofi'set provided by the cylinder directly above the segmental chamber. By a free rotation of the key the pin members 16 will be brought into proper alinement with the openings provided by the barrel.

Having thus fully described the invention, what I claim as new is In combination with a hand cufi' having a pivoted shackle and means for locking the shackle within the body of the cuff, said I the pin lock having its lower portion reduced and formed with an ofiset bit adapted to operate said locking means, the cylinder of the lock being provided with a segmental chamber normally adapted for the reception of the bit, and said chamber communicating with the key-hole opening of the cuff, a resilient element for the barrel to force the same upwardly sothat its pins aline with the pins of the cylinder when the bit is normally sustained within the segmental opening, substantially as and for the purpose set forth.

In testimony whereof I affix my signature in presence. of two witnesses.
